That provides a professional development environment, at least. The code base for the Arduino is another frustration. Bluntly, the use of setup() and loop() with main() being hidden really bugs me.

If you’d like to skip needing to use a second Arduino, we’ve seen some other tools available for debugging Arduino code that can run straight from a connected PC instead.

Arduino users and enthusiasts may be interested in some new tools created by the official Arduino team, to make checking your code as easy as possible.

The Debugger helps you to better understand your Arduino code, and simplifies the debugging process. However, it isn't available for all Arduino boards.
